Abstract: This research was conducted in a greenhouse in Bajío Experimental Station of INIFAP to study the effects of inclusion of fresh raw material dietary on growth performance, food conversion rate, percentage of weight gained and the survival rate in Nile Tilapia fry. The diets consisted are as follow: 1) 60% commercial feed + 40% live worm; 2) 50% commercial feed + 40% live worm + 10% alfalfa dry leaf; 3) 60% commercial feed + 40% beetle larvae; 4) 60% commercial food + 40% beetle larvae; 5) 100% commercial feed. The fresh raw material levels positively influenced (P > 0.05) the specific growth rate and final weight. The growth parameters studied indicate that diets formulated with ingredients of plant and animal origin were the best diets for tilapia fry during the growth period. These results indicate that the fresh raw material could be incorporated in the diet of Tilapia fry with cost benefit.

Abstract: The aim of the study is to determine the effects of different plane of nutrition during late pregnancy to lactation on the performances of ewes and their offspring to weaning. About 36 native Bengal ewes of last 7 weeks gestation were randomly assigned to four different groups (T0, T1, T2, T3). The T0, T1, T2 and T3 groups were supplemented a concentrate mixture at 0.0, 1.0, 1.5 and 2.0% of their body weight, respectively. Chopped German grass (Echinochloa polystachya) was provided as basal forages to ewes and a creep mixture (20 g/lamb/day) to the lambs from 2 weeks of age with a weakly increase of 10 g/lamb. The results shown that ewes dry matter intake (p < 0.01), milk yield (p < 0.05), days open (p < 0.01), live weight gain before lambing (p < 0.01) and at weaning (p < 0.01) and weight recovery from late gestation to weaning (p < 0.05) improved with high plane of nutrition. Higher weight recovery found in T2 group. Litter size had an effect on (p < 0.01) all weight traits of lambs and ewes milk yield. Sex of lamb also affects (p < 0.05) the weaning weight and daily gain of lambs.
